Grilling a whole tenderloin is an art that yields succulent and flavorful results. Whether you are hosting a backyard barbecue or planning a special dinner, this technique promises to impress your guests. In this article, we will guide you through the process of grilling a whole tenderloin to perfection.

Choosing the Right Cut

When it comes to grilling a whole tenderloin, selecting the right cut of meat is crucial. Look for a well-marbled piece with a bright red color. The marbling ensures tenderness and juiciness, while the color indicates freshness. It’s best to purchase the whole tenderloin as a whole piece instead of pre-cut steaks to have more control over the cooking process.


Trimming and Seasoning

Before grilling, it’s essential to trim any excess fat or silver skin from the tenderloin. This step allows for even cooking and prevents flare-ups on the grill. Once trimmed, generously season the meat with your favorite rub or a simple mixture of salt, pepper, and garlic powder. Let the tenderloin sit at room temperature for about 30 minutes to allow the flavors to penetrate.

Preheating the Grill

While the tenderloin is marinating, preheat your grill to medium-high heat. This will ensure a nicely seared exterior and a juicy interior. If using a gas grill, set the burners to medium-high. For charcoal grills, allow the coals to become ash-covered and spread them out evenly.

Grilling Technique

Place the seasoned whole tenderloin on the grill and close the lid. Grill the tenderloin for about 15-20 minutes, turning it occasionally to achieve an even sear. The internal temperature should reach 125°F for medium-rare or 135°F for medium. Use an instant-read thermometer to accurately gauge the temperature.

Resting and Serving

Once the whole tenderloin reaches the desired temperature, remove it from the grill and let it rest for at least 10 minutes. This resting period allows the juices to redistribute, resulting in a more tender and flavorful meat. After resting, slice the tenderloin into thick medallions and serve it with your favorite side dishes.


A whole tenderloin pairs exceptionally well with a variety of accompaniments. Consider serving it with a creamy horseradish sauce, a tangy chimichurri, or a rich red wine reduction. Additionally, roasted vegetables, mashed potatoes, or a fresh spinach salad make excellent side dishes to complement the tenderloin’s flavors.


Grilling a whole tenderloin is a surefire way to impress your guests and indulge in a mouthwatering feast. By choosing the right cut, preparing it with care, and following the grilling technique, you can achieve a perfectly cooked tenderloin every time. So, fire up the grill, gather your loved ones, and savor the deliciousness of a whole tenderloin cooked to perfection!
